Overnutrition during the early postnatal life,a critical time window for growth and development,may induce metabolic syndrome later in life,including overweight/obesity and insulin resistance.The important target organs of insulin,such as liver,adipose tissue,skeletal muscle,and central nervous systems show insulin resistance.The involved mechanisms include abnormality of insulin signal pathway,increment of free fatty acid and some adipocytokines,oxidative stress,maladjustment of orexigenic and anorexigenic neuron,modifications of the hypothalamic-pituitary-adrenal glucocorticoid axis as well as epigenetic,etc.Hence,overnutrition should be avoided during the early postnatal life,so as to decrease the risk of developing long-term insulin resistance.

Objective To explore the effects of recombined human growth hormon-enhanced early enteral nutrition on healing of the patients after operation for sereve abdominal trauma.Methods 60 patients with severe abdominal trauma were randomly divided into PN(n=20),EN(n=20) and EN+ rhGH(n=20) groups.Nutrient status and immune function of 3 groups were detected on the postoperative day 1,7 and 10.Results EN+ rhGH group showed more effective process than EN and PN groups in improving postoperative nutrient status,immune function and nitrogen balance,whose indexs except CD8 changed significantly on the postoperative day 7 and 10 than that in PN group(P

Objective To explore the diagnosis and treatment of gastroparasis syndrome after abdominal operation. Methods Clinical data of 25 cases with gastroparasis syndrome after abdominal operation from Jan 1995 to June 2006 were analysed retrospectively. Results Gastrectomy and nongastrectomy amounted to 16 and 9 cases( portal-azygous vein disconnection in 4 cases, panceaticoduodenectomy in 1 case, partial small intestinectomy and adhesions lysis in 1 case, radical excision of colon carcinoma in 2 cases, choledocholithotomy in 1 case). Gastroparasis syndrome characterized by upper abdominal distension, nausea, vomiting after clipping the pipe or large quantity of gastric drainage after operations. Gastrointestinal series and gastroscopy confirmed functional delayed gastric emptying. All cases recoverd through non-operative therapy including fasting, continuous gastrointestinal decompression, total parenteral nutrition or enteral nutrition, adn administration of gastro-intestinal dynamic medicine. Conclusions Gastroparasis syndrome is the common complication after abdomianl operation, gastrointestinal series, gastroscopy are main diagnostic methods, conservative medication obtains good effect.

Objective To discuss the correlation factors of locally recurrent gastric carcinoma. Methods Clinical, pathological and periodical follow-up datas of 50 cases with locally recurrent gastric carcinoma after radical resection from 1991 to 2005 were studied retrospectively, logistic regression analysis was used to disscuse the possible correlation factors of locally recurrent gastric carcinoma. Results 66.0% of 50 cases had recurrenced within 2 years after operations; Tumor pathological stages, positive lymph nodes and radical resection extent were independent correlation factors of locally recurrent gastric carcinoma. Conclusions Most recurrences would happen within 2 years after radical resection for gastric carcinoma; Early diagnosis of reccurrent gastric carcinoma depends on periodic follow-up observation especially gastroscope; Tumor pathological stages, positive lymph nodes and radical resection extent are independent correlation factors of locally recurrent gastric carcinoma.

Objective To analyze blood-CSF barrier and cerebrospinal intrathecal IgG synthesis in patients of multiple sclerosis, and explore the Protis software, IgG index and IgG synthesis rate in the and evaluation for cerebrospinal intrathecal IgG synthesis and blood-CSF barrier dysfunction. Methods 134 patients with neurological diseases were divided into threes groups, including multiple sclerosis group (34 cases), disease control group(80 cases) and control group(20 cases). IgG and ALB concentration of CSF and blood was detected by BN-Ⅱ. The oligoclonal IgG was detected by immunofixation electrophoresis. The relationship between Protis software results and IgG index or IgG synthesis rate was calculated and analyzed. Results The function of blood-brain barrier was almost normal in multiple sclerosis group,QALB was 4.5×10-3[(3.1-7.6)×10-3], there was no significance compared with control group (D=5.25, P>0.05). there were 31 patients with oligaclonal bands in cerebrospinal fluids in multiple sclerosis group (34 patients) with the positive rate of 91.2%. In multiple sclerosis group the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 31.25% (11.65%-71.45 %), 0.93% (0.80%-1.04%), 24.25 mg/24 h(15.25-46.15 mg/24 h) ,the results were all higher than that in control group (D=175.5, 112.5,103.4,P<0.05). And in multiple sclerosis group there was no significant difference among the intrethecal IgGIF, IgG index and IgG synthesis rate of 24 hours, the positive rate of oligaclonal bands (P>0.05). In disease control group(80 patients) QALB Was 35.2×10-3[(18.5-55.5)×10-3] ,the result was significantly higher than control group (D=102.7, P<0.05), the oligaclonal bands were all negative, IgG index and IgG synthesis rate of 24 hours were 0.75(0.69-0.82) ,44.29 mg/24 h(20.35-65.98 mg/24 h) were both higher than control group(D=85.6,98.5,P<0.05). In disease control group the positive rate of intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours were 0 (0/80), 40.0% (32/80), 72.5% (58/80) respectively, IgG index and its positive rate both increased alone with the lesion degree of blood-brain barrier increasing (P<0.05). And there was similar trend in the IgG synthesis rate of 24 hours. There were significant correlations among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in multiple sclerosis group (r=0.788, 0.695 ,P<0.05). However there was no correlation among intrathecal IgGIF, IgG index and IgG synthesis rate of 24 hours in disease control group (r=0.000,P>0.05). Conclusions The Protis software can be used to analyze the intrathecal IgGIF and reflect the actual status of intrathecal IgG synthesis more accurately. Protis software has great application value for clinical diagnosis for nervous system disease.

Objective To evaluate and monitor the efifcacy of GnRH analogs (GnRHa) therapy. Methods Thirty girls with central precocious puberty diagnosied by LHRH stimulation test were treated with GnRHa for 6-24 months. The LHRH stimula-tion test were performed again at 3 months after initiation of therapy and then every 6 months during treatment. The relationship of peark LH and clinical suppressing pubertal (including Turner stage, bone age, grwoth speed) were compared. The monitor effect of peak LH to efifcacy of GnRHa were eveluated. Results Ninety LHRH stimulation tests were performed, only 7 cases were found to have clinical pubertal development. After 6 months treatment, the base LH level of thirty girls (0.48±0.20) IU/L was signiifcantly lower than that before the treatment (0.75±0.35 IU/L) (P=0.000). The correlation coefifcient between base LH and peak LH was 0.62. The best correlation between clinical suppressing pubertal and LHRH stimulation test was achieved when peak LH was less than 2 IU/L (85.7%sensitivity, 100%speciifcity). Conclusions Base LH value can be used in preliminary as-sessment of the efifcacy of GnRHa therapy for girls with central precocious puberty. The peak LH less than 2 IU/L can be as the indicator of treatment efifcacy.

At present,transplantation has been the predominant way to solve most of the end-stage diseases,ensued by the use of immunosuppressive drugs.Since the immunosuppressive drugs have narrow therapeutic index,the blood drug concentration is needed to mornior.Pharmacogenetics is one subject which focuses on the interaction between gene and the metabolism of the drug,providing great help for designing the regime of achieving the target drug concentration.Meanwhile,it facilitates the realization of individual therapy.This review thus focuses on the latest advancement on the pharmacogenetics of those immunosupprressants,hoping to provide help for the treatment.
